Message recall notification not work in Exchange Online for one domain

But what could be the reason for such behavior as the problem affecting only one domain users only when they are trying to recall email from another domain users in same tenant.

In my scenario i have two customer SMTP domains in same tenant (Suppose Customer A & B) and when A domain user send any mail to B SMTP domain users and trying to recall email from B then A able to get the Success or failure notification but vice versa its not working.

Both SMTP domain users (e.g test@abc.com & test2@def.com) are on Office365 but still vice-versa message recall notification functionality not working.


Message get recalled successfully vice versa but the only problem is with success or failure notification email that is not working in case on 1 SMTP domain.
